What happened to Jolin Tsai G-cup?

Jolin Tsai was attending Hermes promotion event in Hong Kong last night - "Hermes Asia Star Exhibition 2008", when she was spotted by the media with a flatter chest than her last seen G-cup size. The Hong Kong and Taiwanese media are all wondering in great amazement to the discovery.In an earlier photo on file (see pic below), she was shot with her rumoured under plastic surgery G-cup breast held firm.
When Jolin Tsai was asked if she sympathized with Edison Chen's exclusion in the event, she was heard saying,"We still have a lot of stars here."

Jolin Tsai was one of the rumoured women involved in Edison Chen's sex photo scandal though her photos were not circulated and she had strongly denied her involvement.
